Title: MySQL SHOW GRANTS Pasword Hash Disclosure Vulnerability
Severity: LOW
Description:
A vulnerability exists in MySQL versions after 3.23.2 and prior to 3.23.31.
The SHOW GRANTS query is used to list user database privileges.
Included in the output of this command are databse users' encrypted passwords.
If an attacker were to obtain this information, it could be used to obtain plaintext passwords via a dictionary attack.
In vulnerable distributions of MySQL, there are no restrictions on which users can execute this query. Therefore any user who has access to the database can obtain encrypted passwords from the user table.
This may lead to an elevation of database privileges for the attacker if another account's password is successfully cracked.
